[0002] This invention relates generally to an apparatus which is
convertible from a portable cargo container to a wheeled vehicle, and
more particularly, but not exclusively, to a backpack or article of
luggage that includes a deployable wheeled platform so that the backpack
or luggage is convertible to a scooter type vehicle. Some embodiments of
the present invention are particularly useful for transporting relatively
heavy loads along with a human operator, quickly and with minimal effort.

BACKGROUND OF THE INVENTION

[0003] The subject matter discussed in the background section should not
be assumed to be prior art merely as a result of its mention in the
background section. Similarly, a problem mentioned in the background
section or associated with the subject matter of the background section
should not be assumed to have been previously recognized in the prior
art. The subject matter in the background section merely represents
different approaches, which in and of themselves may also be inventions.

[0004] Backpacks and articles of luggage combining wheels and retractable
pull handles are well known in the art. Although these devices aid in
transporting cargo, they do not aid in transporting a human operator.

[0005] Likewise, foldable scooters and bicycles as disclosed in U.S. Pat.
No. 3,680,879 are also well known in the art. These devices provide a
convenient means of transporting a bike or scooter, but do not provide an
operator the ability to carry any cargo.

[0006] Other portable wheeled devices known in the art are described in
U.S. Pat. No. 6,155,579 which discloses a foldable child stroller and
U.S. Pat. No. 5,791,670 which discloses an article carrying device. U.S.
Pat. Nos. 5,609,278, 5,984,154, 5,483,495, 6,179,176, 4,036,336,
5,749,503, 5,881,932, and 5,743,447 all disclose wheeled carrying devices
with alternative carrying devices.

[0007] Convertible backpacks that also function as rideable scooters can
be susceptible to folding and loading that sometimes pose physical risks
to users. Some physical risks include folding and scissoring components
that, without attention, may lead to pinching risks as a user transitions
between the various modes.

[0008] Further, many deck transition/attachment systems can lead to
unstable connections when the deck is open. It can be the case that the
coupling that enables the end of the deck to fold for storage, also means
that the attachment can be a point of failure during riding. Failure
modes include instability or premature folding, particularly when a rider
pushes forward, or pulls back, on a steering mechanism.

[0009] In some implementations having a backpack and a folding deck
engaging a back of the backpack, the deck and folding hardware can add a
significant distance between the backpack pack and the wearer. This
distance can degrade the quality of the backpack function of being worn
on the back and carrying items because the items extend too far away from
the user.

[0010] An important consideration for some users is the ease by which a
deck is transitioned between a closed mode and an open mode. For these
users, a simple one-handed operable latching mechanism is superior.
Unfortunately, for any latching solutions attempting to address other
concerns identified herein, it can be a challenge to also maintain
desired simplicity.

[0011] What is needed is a backpack or article of luggage that includes a
deployable wheeled platform so that the backpack or luggage is
convertible to a scooter type vehicle, preferably while reducing the
drawbacks identified herein.

BRIEF SUMMARY OF THE INVENTION

[0012] The following summary of the invention is provided to facilitate an
understanding of some of technical features related to a backpack
including a deployable wheeled riding platform, and is not intended to be
a full description of the present invention. A full appreciation of the
various aspects of the invention can be gained by taking the entire
specification, claims, drawings, and abstract as a whole. The present
invention is applicable to other types of luggage and other deployable
wheeled platforms.

[0013] Overcoming these problems by providing a convertible cargo
container with a deployable wheeled platform is a primary objective of
the present invention. Other objects of the invention will become
apparent in light of the following disclosure and related claims.

[0014] A combination scooter, pull-pack, backpack with three user
transportation modes: riding, pulling, and carrying. The Product design
incorporates the following combination of unique characteristics and
components: An integrated three-wheeled scooter where, in ride mode, one
wheel is located at the front end of the cargo carrier, and the other two
wheels are located at the rear of a deployable riding platform so as to
be functional in both ride mode with the platform deployed, and in pull
mode with the platform retracted; an integrated cargo carrier component;
a fully deployable and retractable riding platform with an integrated
linkage between the cargo carrier and platform such that all three wheels
remain in contact with the ground allowing the cargo carrier to remain
standing upright while transforming between open and closed positions, as
well as through the transition between these positions; an integrated
roller(s) mechanism on the end of the platform that allows the platform
to easily roll up and down between open and closed positions; a latching
mechanism(s) integrated into the platform that allows the platform to be
secured in both open and closed positions; an offset steering mechanism
with a linkage to the front wheel chassis allowing the rider to turn the
scooter's front wheel free of the cargo payload weight resistance in
order to achieve the desired turn; integrated strap(s) for carrying the
entire unit when riding and pulling aren't convenient; an integrated and
vertically adjustable handlebar component; and an integrated friction
brake pedal on the rear of the platform that slows both rear wheels when
depressed in ride mode.

[0015] Embodiments of the present invention is generally comprised of
three main components, a cargo container 1, a handle 4, and a retractable
platform 7 having wheels 10, which can be converted to three basic modes,
a backpack, wheeled luggage, and a scooter type vehicle. The first
backpack mode is suitable for carrying light loads or loads over rough
terrain. The second wheeled luggage mode is most suited to carrying cargo
in medium traffic areas with generally flat terrain, such as an airport.
The third scooter type vehicle mode is well suited to transporting a load
as well as the operator great distances over low traffic areas with
generally flat terrain. The third scooter type mode is also particularly
advantageous when time is of the essence. The invention thus overcomes
several problems associated with manually hauling cargo efficiently,
while also providing a means to transport an operator along with the
payload.

[0016] A mobility cargo platform includes a vertically extending central
main support having a longitudinal channel extending from a bottom end to
a top end and a track assembly disposed along an outside of the
vertically extending main support extending upwardly from a first
location proximate the bottom end to a second location toward the top
end; a steering handle rotatably disposed inside the longitudinal channel
and extending from the bottom end above the top end controlling a
direction; a steerage linkage coupled to the steering handle at the
bottom end and extending in a first direction away from the vertically
extending central main support; a steering wheel assembly, coupled to the
steerage linkage; a stowable rider deck having a proximal end including a
track engagement assembly coupled to the track assembly and a distal end
coupled to a rear wheel assembly, the stowable rider deck repeatably
transitionable between a closed mode in which the proximal end is
proximate the second location with the rider deck generally vertical and
an open mode in which the proximal end is proximate the first location
with the rider deck generally horizontal; a cargo container coupled to
the vertically extending central main support; and a latching assembly,
coupled to the stowable rider deck, securing the stowable rider deck in
the closed mode.

partially mentioned or alluded to or are not mentioned or alluded to at
all in this brief summary or in the abstract. Although various
embodiments of the invention may have been motivated by various
deficiencies with the prior art, which may be discussed or alluded to in
one or more places in the specification, the embodiments of the invention
do not necessarily address any of these deficiencies. In other words,
different embodiments of the invention may address different deficiencies
that may be discussed in the specification. Some embodiments may only
partially address some deficiencies or just one deficiency that may be
discussed in the specification, and some embodiments may not address any
of these deficiencies.

[0018] Other features, benefits, and advantages of the present invention

DETAILED DESCRIPTION OF THE INVENTION

[0095] Embodiments of the present invention provide a system and method
for a backpack or article of luggage that includes a deployable wheeled
platform so that the backpack or luggage is convertible to a scooter type
vehicle, preferably while reducing the drawbacks identified herein. The
following description is presented to enable one of ordinary skill in the
art to make and use the invention and is provided in the context of a
patent application and its requirements.

[0096] Various modifications to the preferred embodiment and the generic
principles and features described herein will be readily apparent to
those skilled in the art. Thus, the present invention is not intended to
be limited to the embodiment shown but is to be accorded the widest scope
consistent with the principles and features described herein.

[0097] Embodiments of the present invention include a cargo container
which can be converted into a scooter type vehicle for transporting a
person and his cargo. Embodiments generally include three main
components, a cargo container 1, a handle 4, and a retractable platform 7
having wheels 10. The invention has three use positions including riding,
as shown in FIGS. 1-3, pulling/pushing, as shown in FIGS. 6-7 and
carrying as shown in FIGS. 8-9.

[0098] Referring specifically to FIGS. 1 and 2, the convertible cargo
container is seen in its ride mode having retractable platform 7 deployed
to a position substantially perpendicular to cargo container 1. The cargo
container 1 can be manufactured of hard shell plastic such as ABS, or
lightweight metal. Wheels 10 are mounted at the outer edges of the lower
end of platform 7. Platform 7 can be made of any suitably light, strong
material such as plastic or thin metal to achieve rigidity and low
weight. Wheels 10 can be fabricated of any suitable polymer, plastic,
rubber, or synthetic rubber. Additionally, it is noted that the platform
could also have a single rear wheel centrally mounted. Telescoping tube
13 is shown in its extended position and handles 4 are pivoted to their
horizontal position about pivots 19 forming a handle bar 16. Telescoping
tube 13 uses spring biases balls and detents so that it can maintain its
extended and retracted positions. Handles 4 can be pivoted to a closed
position as shown in FIGS. 4-10 when it is desired to push/pull or carry
the cargo container. In push/pull or carry mode the platform 7 is
retracted to a position that is substantially parallel to the rear side
of the cargo container. Shoulder straps 34 are mounted on the cargo
container in a conventional manner so that the invention can be carried
as a backpack. Shoulder straps 34 may be detachable or retractable. Door
22 can be pivotally mounted or friction fit to provide access to main
storage compartment 25. Platform 7 deploys along a slot 37 in the cargo
container 1 and is slidably connected to telescoping tube 13 at its upper
end through a sliding bearing 43.

[0099] Telescoping tube 13 is rotatably mounted in the cargo container 1
as is distal end, and is connected to steering assembly 28 as shown in
FIGS. 11-12. The frame of the steering assembly 28 can be rotated in the
cargo container through arcuate slots 29. Front wheel 31 is rotatably
mounted in steering assembly 28. The telescoping tube and steering
assembly can be fabricated from any suitable lightweight metal or
plastic.

[0100] As can best be seen in FIGS. 13-16, a linkage arm 40 pivotally
connects platform 7 to the distal end of telescoping tube 13. In this
manner, platform 7 can be retracted to its push/pull or carry position.

[0101] Operation of the device will now be described. When an operator
wants to transport himself and cargo in scooter mode, the handles 4 are
fully deployed as handle bar 16, and the platform 7 is fully deployed at
a substantially perpendicular angle to the cargo container 1. The
operator stands on platform 7 and steers the device with telescoping tube
13 and the attached steering assembly 28. When a high traffic area is
encountered, the operator would step off the platform and pivot the
handles to their closed position as shown in FIG. 4. Platform 7 would
then be retracted along slot 37 until it is substantially parallel to the
rear side of the cargo container 1 as shown in FIGS. 6 and 7. The
apparatus is now in its wheeled luggage mode and can be transport on
wheels 10 by pushing or pulling the closed handles. When carrying the
apparatus is desirable, telescoping tube 13 is in its fully retracted
position as shown in FIGS. 8-10, and the apparatus can be worn as a
backpack utilizing shoulder straps 34. The bottom of platform 7 may be
contoured to provide the operator lumber support when using the apparatus
in backpack mode. The transition steps are reversed when switching from
backpack mode to scooter mode. It is noted that the order the
transitional steps are performed is not crucial, and may be altered.

[0102] The second embodiment of the invention is similar to the first,
having a cargo container 46, a telescoping tube 58, a platform 52 and
wheels 55 as shown in FIGS. 17 and 18. Telescoping tube 58 is connected
to front wheel 64 through the same steering mechanism described in the
first embodiment. As shown in FIGS. 21 and 22 platform 52 is slidably
mounted on rods 73. Platform springs 70 bias the platform to its extended
position as shown in FIG. 22. A spring biased platform release hatch 67
retains the platform 52 in its retracted position. Rigid handle 49 has
two handle bars 61 which form a central opening. Operation of the second
embodiment is the same as the first except that the platform is deployed
to its extended position by depressing platform release hatch 67, and is
retracted pushing it against the bias of springs 70 until caught by
platform release hatch 67.

[0103] FIG. 23 illustrates a closed isometric view of an alternate
embodiment for a closed convertible backpack, wheeled luggage, and
scooter system, referred to herein for convenience as a mobility cargo
platform 2300. Platform 2300 includes a cargo container 2305, a
retractable, telescoping handle 2310, and a stowable rider deck 2315. The
preferred embodiment for platform 2300 includes three wheels: one
steering wheel (not shown) mounted to a steerage linkage coupled to
handle 2310 so that turning handle results in turning the wheel and
controlling direction, and a pair of multiuse platform rear wheels 2320
coupled to a lower edge of rider deck 2315. As braking assembly 2325,
shown in detail below, includes a pedal actuator 2330 for engaging a pair
of brake pads against rear wheels 2320, and specialized fenders 2335
disposed near rear wheels 2320. A latching system 2340 secures rider deck
2315 in the closed position. A roller assembly attached to rider deck
2315 and a track assembly 2345, coupled to handle 2310, guides transition
of rider deck 2315 as it moves between a closed/retracted position and an
open/extended position.

[0104] FIG. 24 illustrates a top plan view of platform 2300 shown in FIG.
23 with rider deck 2315 opened and extended. A handle lock is shown for
locking handle 2310 in an extended position (shown) or a retracted
position in which handle 2310 is telescoped down (shown in FIG. 26). FIG.
25 illustrates a front plan view of platform 2300 shown in FIG. 23. In
this view, a front steering wheel 2505 (described but not shown in FIG.
23) is coupled to a steering linkage 2510. Steering linkage 2510 helps to
decouple steering ability from cargo weight.

[0105] FIG. 26 illustrates a back plan view of platform 2300 shown in FIG.
23 with the rider deck 2315 closed and handle 2310 retracted and stowed.
In this configuration, platform 2300 is ready for storage or to be
carried as a bag/backpack using one or more straps. Handle lock 2405 is
used to lock/unlock handle 2310 for telescoping. FIG. 27 illustrates a
bottom plan view of platform 2300 shown in FIG. 23 with rider deck open
2315 and extended. Steering linkage 2510 is shown coupling handle 2310 to
front steering wheel 2505.

[0106] FIG. 28 illustrates a side view of platform 2300 shown in FIG. 23
with rider deck 2315 closed, handle 2310 retracted, and platform 2300
stationary and stable on a surface 2805 as it sits on all three wheels.
FIG. 29 illustrates the side view of platform 2300 shown in FIG. 28
tilted into the pull configuration with handle 2310 extended, rider deck
2315 closed, and front steering wheel 2505 lifted up off of surface 2805
as platform 2300 is moved (e.g., pushed or pulled) over surface 2805.
This view highlights one of the special features of fenders 2335: they
are shortened and extend around but a partial arc of rear wheels 2320 so
as to not interfere with surface 2805 as platform is tilted backwards and
moved.

[0107]FIG. 30 illustrates a side view of platform 2300 shown in FIG. 23
with cargo container 2305 removed for clarity and with rider deck 2315
open and handle 2310 extended. FIG. 31 illustrates the side view of FIG.
30 with cargo container 2305 added for context.

[0108] FIG. 32 illustrates a side view of platform 2300 shown in FIG. 23
with rider deck 2315 intermediate its open and closed positions. A distal
end 3205 of rider deck 2315, opposite of a proximal end 3210 where rear
wheels 2320 are attached, glidingly rolls within track assembly 2345 as
it moves up/down to close/open rider deck 2315 (which retracts/extends
rider deck 2315 as well). To close platform 2300, distal end 3205 is
moved up, and as distal end 3205 moves up in track assembly 2345, rear
wheels 2320 move closer to front steering wheel 2505 and rider deck 2315
moves more vertical. To open platform 2300, distal end 3205 is moved
down, and as distal end 3205 moves down in track assembly 2345, rear
wheels 2320 move further from front steering wheel 2505 and rider deck
2315 moves more horizontal.

[0109] FIG. 33 illustrates a detail view of steering linkage 2510 of
platform 2300 shown in FIG. 23. Steering linkage 2510 includes a lower
tube 3305 into which handle 2310 telescopes and within which handle 2310
rotates. A rotation arm 3310 is coupled to the bottom of lower tube 3305
and rotates as handle 2310 rotates. A linkage arm 3315 couples rotation
arm 3310 to front steering wheel 2505. Front wheel is rotatably supported
within a caster/bearing 3320 extending from lower tube 3305 by a bracket
3325. Caster/bearing 3320 can provide shock absorption in some
embodiments. Steering linkage 2510 helps improve safety by making turning
easier when weight is added to platform 2300. Without steering linkage
2510, a user would need to manage the weight with each turn.

[0111] FIG. 36 illustrates a plan view of pedal actuator 2330 of brake
assembly 2325 shown in FIG. 34. Pedal actuator 2330 includes apertures
3605 to pivotally couple to rider deck 2315 and to selectively contact a
brake pad 3610 to each rear wheel 2320. A pair of latches 3615 ensure
that pedal actuator 2330 does not rotate too far upward and accidentally
trip a rider or otherwise interfere with availability for braking. FIG.
37 illustrates an isometric view of brake assembly 2325 shown in FIG. 34
with the brake pedal shown in FIG. 36 removed. FIG. 38 illustrates
operation of the braking system for platform 2300 shown in FIG. 23. A
pair of brake pads 3800 (in some implementations a single pad) make
contact with both (or a single rear wheel) when pedal actuator 2330
(shown in FIG. 23) is depressed. A deck support 3805 includes an aluminum
channel fastened to an underside of platform 2300 to provide structural
rigidity. Pedal actuator 2330 hinges about an axle 3810 mounted to deck
support 3805.

[0112] FIG. 39 illustrates a roller assembly connecting system 3905
coupling rider deck 2315 to track assembly 2345 for platform 2300 shown
in FIG. 23. Roller assembly connecting system 3905 includes an arm 3910
with a pair of rollers that engage a pair of tracks inside track assembly
2345. FIG. 40 illustrates a detail view of roller assembly connecting
system 3905 shown in FIG. 39. A roller 4005 of the pair of rollers is
shown engaging a track 4010 of track assembly 2345. The other roller and
track are mirror images of those shown. FIG. 41 illustrates a first side
sectional view of roller assembly connecting system 3905 shown in FIG.
39. FIG. 42 illustrates a second side sectional view of roller assembly
connecting system 3905 shown in FIG. 39. Arm 3910, roller 4005, and track
4010 are shown.

[0113] In some cases and for some embodiments and applications, there may
be a need or desire to latch rider deck 2315 into the open position. Some
designs can produce undesirable flexing/pivoting about connection points
between rider deck 2315 and track assembly 2345. For example there can be
a forward rotation of handle 2310 while rider deck 2315 is open/extended
and a rider is aboard. FIG. 43 illustrates a plan view for a
representative deck latching system 4305 for platform 2300 shown in FIG.
23. Deck latching system 4305 of the preferred embodiment is designed and
configured to both latch rider deck 2315 open, but also to
reduce/eliminate forward rotation of handle 2310 when platform 2300 is
ridden in scooter mode. Deck latching system 4305 is a sliding bolt latch
design that includes a biased pin for engagement with, and disengagement
from, track assembly 2345.

[0114] FIG. 44 illustrates a plan view for an alternative representative
deck latching system 4405 for platform 2300 shown in FIG. 23. FIG. 45
illustrates a detail plan view of deck latching system 4405 shown in FIG.
44. Deck latching system 4405 includes a pivoting handgrip 4505 that
pulls up to initiate disengagement of deck latching system 4405 from
track assembly 2345 and rotates downward to initiate engagement of track
assembly 2345.

[0116] FIG. 48 illustrates a plan view for an alternative representative
deck latching system 4805 for platform 2300 shown in FIG. 23. FIG. 49
illustrates a detail plan view of deck latching system 4805 shown in FIG.
48. Deck latching system 4805 includes a rotating latch 4905 that rotates
in one direction to initiate disengagement of deck latching system 4805
from track assembly 2345 and rotates in the other direction to initiate
engagement of track assembly 2345.

[0117] FIG. 50 illustrates a deck stop 5000 for platform 2300 shown in
FIG. 23. Deck stop 5000 is part of the connection system between the
rider deck and the track assembly shown and described herein. Arm 3910 is
part of deck stop 5000 and includes an aperture 5005 for mounting the
rollers that move within the tracks of the track assembly. A recess 5010
receives and secures a strut underlying the rider deck to add strength.
Latching mechanisms described herein are responsive to this arrangement
of deck stop 5000. Alternatives to deck stop 5000 may be implemented, for
example, deck stop 5000 may be mounted under the rider deck which allows
removal of a front "hump" shown at the front of the rider deck in some
figures and would permit alternate latching mechanisms to be used.
Additionally, for some designs, the hump may on the distal end of the
rider deck can make wearing platform 2300 in backpack mode uncomfortable
for some users. Alternative structures resulting in reduction/elimination
of the hump or this effect are advantageous.

[0118]FIG. 51 illustrates a deck pull handle 5105 for platform 2300 shown
in FIG. 23. FIG. 52 illustrates an isometric view of an optional backpack
pad 5205 used with platform 2300 shown in FIG. 23. Deck pull handle 5105
is, in some embodiments, integrated into platform 2300, allowing for its
deployment and stowage. Backpack pad 5205 hinges at the top and secures
at the bottom with selective attachment structures (e.g., magnets and the
like) in the folded/closed position.

[0119]FIG. 53 illustrates an alternate deck roller assembly 5300 that is
an alternative to roller assembly connecting system 3905 shown in FIG.
39. Deck roller assembly 5300 includes a "spine" support 5305 (e.g., a
tube for handle 2310 or the like) that includes a pair of integrated
flanges 5310. A roller assembly engages flanges 5310 and includes a
roller 5320. Attachment of rider deck 2315 to assembly 5315 allows
opening/closing similar to that as described herein for other roller
assembly alternatives.

[0120] Other improvements include structures making platform 2300 less
bulky, and lighter, and reducing costs of goods. The figures herein
represent prototypes and initial visualizations of the product and in
some ways are sturdier than required for manufacturing. Some of the
designs reflect prototypes built from 1''-thick solid aluminum stock,
which is unnecessary for manufactured products, but appropriate for
wanting to withstand extended testing and potential failure analysis.
Alternatives suitable for manufacture may include designs inspired from
folding ironing tables (which employ very inexpensive yet reliable
fold-and-slide mechanism) and drawer rail hardware. The latter are made
out of punched and formed steel and are rated to support considerable
load. Also, they roll on inexpensive nylon rollers which could help the
platform deploy smoothly. These two points of departure or inspiration
alone would help reduce complexity, bulk, weight and expense
considerably.

[0121] Specifics of shoulder/carrying straps have not been shown as they
may implemented in many different ways. A preferred implementation
includes straps mounted to a side of cargo container 2305 supporting
rider deck 2315. A pair of straps are provided on lateral sides of rider
deck 2315, connected at a top and at a bottom of cargo container 2305.
For straps disposed on that side of cargo container 2305, it is
advantageous to provide for a strap management system to inhibit having
straps interfere with use during ride and pull modes. Strap management
may be fairly basic, including a retaining system for the straps and
cargo container such as hook-and-loop mating patches that removeably
attach the straps to the cargo container and reduce interference. More
exotic systems of buckles and retainers may be used to more securely and
aesthetically retain the straps when not needed or desired, such as for
carrying platform 2300.

[0122]FIG. 54-FIG. 73 illustrate alternative embodiments for a backpack
framework 5400 with a deployable wheeled rider deck (or platform) 5405.
FIG. 54 illustrates a rear perspective view of the alternative embodiment
in an open mode. FIG. 55 illustrates a rear perspective view of the
alternative embodiment in an intermediate mode. FIG. 56 illustrates a
rear perspective view of the alternative embodiment in a closed mode.
Backpack framework 5400 is configured for use with a removable backpack
(not shown) supported by a backpack support/steering shroud 5410.
Backpack framework 5400 is shown without the backpack to better visualize
the components and their operation. It is preferred that a user be able
to detach the backpack from backpack framework 5400 and use the backpack
in standalone fashion, while preserving an option for its use. In other
implementations, the backpack is not required to be removable, such as
having backpack framework 5400 integrated into the backpack, luggage,
container, or the like.

[0123] As described herein, platform 5405 is moveably engaged with a main
tube 5415 that extends generally vertically from support/shroud 5410
(some embodiments may provide a strictly vertical arrangement while other
arrangements may configure main tube with a slope). Platform 5405
includes a coupling that enables a proximal end 5420 (via a lateral
linkage) to travel along a track assembly (in this embodiment one or more
(preferably a pair of opposing) lateral rails), herein referred to as
lateral rails 5425 when transitioning platform 5405 between the open mode
and the closed mode. A latching mechanism 5430 locks platform 5405 into
the open mode. Latching mechanism 5430 operates by use of a simple latch
handle 5435 to unlock platform 5405. This enables single-handed
manipulation and operation to transition platform 5405 between the modes.
The coupling may include one or more sliders, rollers and the like.
Additionally, the track assembly may include a wide-range of different
rails, channels, guides, and the like, in addition to or in lieu of the
particular implementation shown and described herein.

[0124] Platform 5405 includes one or more (preferably a pair) of wheels
5440 at a distal end 5445. One or more (preferably one) steering wheel
5450 is coupled to main tube 5415 by a steerage linkage to enable safe
steering by virtue of a steering handlebar 5455 rotatably coupled to the
steerage linkage through main tube 5415. A preferred implementation
includes provision of the three wheels as described which enables a user
to maintain all three wheels in contact with the ground in either the
open mode or the closed mode.

[0125] Representative attachment points, for example a plate 5460, are
shown to support repeatable (de)attachment of a backpack to backpack
framework 5400. (Other attachment points may be disposed on other parts,
for example, along a perimeter of support/shroud 5410.)

[0126] In FIG. 55, backpack framework 5400 is transitioning from the open
mode (e.g., FIG. 54) to the closed mode (e.g., FIG. 56). Proximal end
5420 slides up and down along lateral rails 5425 to fold/unfold platform
5405. In FIG. 56, platform 5405 is completely folded against main tube
5415.

[0127] FIG. 57 illustrates a side view of the alternative embodiment in
the open mode. FIG. 58 illustrates a side view of the alternative
embodiment in the intermediate mode. FIG. 59 illustrates a side view of
the alternative embodiment in the closed mode. FIG. 58 presents a linkage
5805 that, similarly to linkage 40 in FIG. 14, couples platform 5405 to
main tube 5415. The attachment may be with one or more rollers or sliders
or the like. While linkage 5805 provides advantages in operational
stability and safety, linkage 5805 is a potential source of a pinch
hazard, depending upon an interrelationship and interaction of linkage
5805 with other components. Some embodiments may include an option to
releasably couple linkage 5805 to one or more of platform 5405 and main
tube 5415. This allows linkage 5805 to release and separate rather than
catch and injure any finger or other appendage. Other protection systems
include use of a protective shroud.

[0128] Support/shroud 5410 serves a dual purpose in supporting a backpack
as mentioned, and surrounding and inhibiting access to the steerage
linkage. The steering linkage could be an additional pinching hazard.
There are other potential hazards that may be shielded with a shroud. For
example, a roller/linkage slider 5810 that engages lateral rail(s) 5425
and rolls/slides may in some implementations be considered to produce a
pinch hazard. Use of a shroud 5815 can reduce such pinch hazards and
improves the safety of such devices.

[0129] Also as seen in FIG. 58, use of roller/slider(s) 5810 and lateral
rail(s) 5425 moves platform 5405 and its connection to main tube 5415
forward from rear connection and allows for use of simple latching
mechanism 5430 and one-handed transition.

[0130]FIG. 60 illustrates a top view of a portion of the wheeled rideable
platform 5405 engaging main tube 5415. FIG. 61 illustrates a top view of
a pair of lateral rails 5425 used in FIG. 60. A portion of a steerage
linkage 6005 is shown in FIG. 60. Steerage linkage 6005 is coupled to the
front wheel and is operated by handlebar 5455 through main tube 5415.

[0131] FIG. 62 illustrates a close-up section of a front perspective view
of the alternative embodiment. The close-up is of backpack framework 5400
in the open mode and latching mechanism 5430 engaged and securing
platform 5405 open. FIG. 63 illustrates a bottom perspective view of the
section illustrated in FIG. 62.

[0132]FIG. 64 illustrates the bottom perspective view of the section
illustrated in FIG. 63 without support/shroud 5410. Steerage linkage 6005
is shown coupling handlebar 5455 to front steering wheel 5450. Turning
handlebar 5455 turns front wheel 5440 by virtue of linkage 6005. This
arrangement enables safe turning and makes it so that turning is
independent of the weight and arrangement of the cargo. Without linkage
6005, a user would need to "lift" the weight of the cargo for every
course correction, increasing risk as the load increases.

[0136]FIG. 69-FIG. 73 illustrate details of latching mechanism 5430 in
latched and unlatched positions. FIG. 69 illustrates a perspective view
of the latch mechanism in the latched position. FIG. 70 illustrates a
side view of the latch mechanism of FIG. 69. FIG. 71 illustrates a
perspective view of the latch mechanism in the unlatched position. FIG.
72 illustrates a side view of the latch mechanism of FIG. 71. Latching
mechanism includes a housing 6905 that allows proper arrangement,
orientation, and operation of the component parts. These parts include a
latch 7005, a latch handle lever 7010, a compression spring 7015, and
latch handle 5435. Compression spring 7015 biases latch 7005 in the
locked position and latch handle 5435 downward. Lifting latch handle 5435
overcomes the biasing and moves latch 7005 to the unlocked position.
Latch 7005 includes a beveled end to enable transition of the platform
from the closed mode to the open mode to automatically lock without
lifting latch handle 5435. On the main tube there is a complementary
latch engagement structure that latch 7005 engages in the locked
position. The beveling allows automatic locking as latch 7005 contacts
the latch engagement structure but ensures positive latching so that
locking mechanism 5430 may only be unlocked by manually and intentionally
lifting latch handle 5435.

[0137] During operation, unlocking latching mechanism 5430 by lifting
latch handle 5435 simultaneous unlocks the platform and provides the user
with a handle to continue the motion and in a single action lift and
close the platform. Lifting latch handle 5435 causes latch handle lever
7010 to withdraw latch 7005 and move it against compression spring 7015,
thereby disengaging the lock mode.

[0138] FIG. 73 illustrates backpack framework 5400 in the open mode
including a side cross-section of engagement of latch mechanism in the
latched position. Shown in FIG. 73 is a complementary latch engagement
structure 7305 that interacts with latch 7005 to lock and unlock latching
mechanism 5430, and platform 5405.

[0139] Optionally, the cargo container of any embodiment can be made of a
suitably durable synthetic or natural fabric shell or it can be formed of
a synthetic or natural fabric shell mounted over a rigid frame.
Additionally, either embodiment can have a power source such as an
electric or gas motor mounted in the platform or cargo container.
